Description

Technical Field

[0002] At present, in the field of logistics and transportation technology, platform cargo loading and unloading operations are an important link in undertaking upstream warehousing and downstream transportation. However, most platform cargo loading and unloading operations are still mainly manual, which is time-consuming and labor-intensive, with poor loading and unloading efficiency, and there are problems such as high cargo damage rate and insecurity.

[0003] Traditional cargo lifting and transfer equipment usually divides the lifting, transfer and stacking of cargo into different stages. Each stage may require different equipment or manual intervention. Lifting and stacking need to be performed in sections, and the process is fragmented. The cargo transfer requires manual adjustment of the inclination angle, and it needs to be lifted piece by piece, with a long operation cycle. At the same time, during the cargo stacking process, there may be problems such as misplacement and uneven stacking of cargo. When the stacking height increases, it may become unstable or tilted. It operates intermittently, relies on manual calibration, and has a slow processing speed. Especially when the weight of the stacked cargo increases, the stability of the equipment may be affected. Traditional equipment usually requires manual intervention for adjustment or monitoring operations. Summary of the Invention

[0022] The present invention provides a cargo lifting and stacking automatic transfer device. It has the following beneficial effects:

[0023] 1. The present invention has a space-intensive layout: the bottom frame and the top frame are staggered, and the top frame is installed on the side of the bottom frame to form a top angle area. This not only avoids the vertical overlap of the two frames and occupies space, but also provides a lifting buffer space for the lifting and stacking mechanism, reducing the overall volume of the equipment. The input guide roller group is embedded in the side wall of the bottom frame, and the goods are directly introduced into the receiving guide roller mechanism from the external conveyor line, reducing the lateral extension space requirement of traditional transfer equipment.

[0024] 2. The present invention has the ability of continuous and efficient transfer: the drive chain circulates along the elliptical rack, driving multiple sets of reciprocating jacking mechanisms to operate continuously, realizing uninterrupted operation of the entire process from receiving, jacking to palletizing of goods. The efficiency is improved compared with traditional single lifting equipment. Multiple sets of reciprocating jacking mechanisms are distributed at intervals, and each set of mechanisms independently completes the lifting of goods, forming a "receiving-jacking-releasing" assembly line operation.

[0025] 3. The present invention has dynamic height adjustment and stacking stability: the lifting and stacking mechanism controls the lifting and lowering of the parcel linkage frame through the screw output structure, can adjust the transfer height in real time, adapt to the buffering and constant pressure output of the scissor-type bracket required for different stacking heights, and the scissor-type bracket and the retaining spring of the step-by-step descending assembly work together to make the output guide roller group sink at a uniform speed when the goods are stacked, buffering the impact force of the falling goods and preventing the stacking from tipping over.

[0026] 4. The present invention has the ability of precise positioning and adaptive alignment: the inclined surface design of the trapezoidal guide frame in the receiving guide roller mechanism allows the input goods to be automatically aligned and gathered into rows on one side of the guide roller frame, eliminating the need for manual adjustment. The lifting rollers of the reciprocating lifting mechanism are precisely embedded in the gap between the guide roller frames to avoid deviation or jamming during the lifting process of the goods.

[0027] 5. The present invention has the functions of mechanism linkage and intelligent reset: the conical interference block of the lifting and stacking mechanism contacts the traction link at a specific height, forcing the lifting roller to tilt and guiding the goods to slide into the central inclined platform, realizing the automatic switching of "horizontal lifting → inclined unloading". The quick reset system driven by the retaining spring, after the traction link is separated from the conical interference block, the retaining spring drives the linkage rod to reset to the horizontal state, ensuring the continuity of the next cycle of operation.

[0028] 6. The present invention has modularity and maintainability: the core components such as the bottom frame, top frame, guide roller frame are connected by bolts, which support quick disassembly and replacement. The independent drive unit layout, drive chain, screw output structure, scissor bracket and other power units operate independently in different areas to avoid mechanical interference.

[0045] Please see the attached Figure 1 -Attached Figure 6The receiving guide roller mechanism 6 is located on the elliptical rack 3 and is used to receive and linearly guide the goods to be transferred. The receiving guide roller mechanism 6 includes a side frame 61 and a guide roller frame 62. The side frame 61 is fixedly connected to the side of the bottom rack 1 away from the elliptical rack 3. The guide roller frame 62 is equidistantly distributed and rotatably connected to the side frame 61.

The receiving guide roller The side frame 61 included in the mechanism 6 is installed on the side of the bottom frame 1 away from the elliptical storage rack 3, so that the elliptical storage rack 3 fixed on the top frame 2 and the drive chain condition 4 can operate in independent areas, and the other ends of the multiple groups of guide roller frames 62 added to the side frame 61 are installed on the bottom frame 1 through independent bracket structures, so that the gap area between adjacent guide roller frames 62 is open, and the trapezoidal guide frame 63 added to the side frame 61 is attached to the surface of the guide roller frame 62, and its inclined surface can guide the goods delivered by the input guide roller group 5 to align and approach one side of the guide roller frame 62, and gradually gather into a row on the side of the guide roller frame 62 close to the elliptical storage rack 3.

[0046] Please see the attached Figure 1 -Attached Figure 10The reciprocating lifting mechanism 7 is located on the driving chain condition 4 and cooperates with the guide roller frame 62 to continuously lift the goods to be transferred in a reciprocating manner. The reciprocating lifting mechanism 7 includes an opposing linkage frame 71 and a linkage shaft 72. The opposing linkage frame 71 is an L-shaped protruding structure and a card shaft structure is provided on one side and is installed adjacent to the linkage shaft 72. The opposing linkage frame 71 and the linkage shaft 72 card shaft structure are fixedly connected with a card angle piece 73 at both ends. The card angle pieces 73 are connected to each other by chain links. The opposing linkage frame 71 and the linkage shaft 72 fit on the chain shaft of the driving chain condition 4 through the card angle piece 73. A horizontal connecting rod 74 is connected between the card shaft structure of the opposing linkage frame 71 and the linkage shaft 72. The opposing linkage frame 71 rotates on the side away from the card shaft structure. The cam 76 is fixedly connected to the locking cam 77 at the top and the locking cam 78 is fixedly connected to the cam 77 at the bottom. The hook 72 is provided with an extension roller structure, and the reciprocating jacking mechanism 7 includes an adjacent opposed linkage frame 71 and a linkage shaft 72, and the clamping shaft structure of the opposed linkage frame 71 and the clamping angle pieces 73 installed at both ends of the linkage shaft 72 are connected to each other by a chain link structure, so that when the clamping angle piece 73 is installed on the chain of the drive chain condition 4, it can bend according to the turning part of the chain, so that the clamping angle piece 73 can pull the opposed linkage frame 71 and the linkage shaft 72 to follow the chain end displacement of the drive chain condition 4, and the horizontal connecting rod 74 sleeved between the linkage shaft 72 and the clamping shaft structure of the opposed linkage frame 71, so that when the opposed linkage frame 71 and the linkage shaft 72 follow the clamping angle piece 73 to move to the vertical end of the chain structure of the drive chain condition 4, they can move along The linkage shaft 72 props up the opposing linkage frame 71 to a horizontal state, so that when the opposing linkage frame 71 is displaced vertically, it always keeps itself rising horizontally, and the linkage fixed shaft 75 installed at the outer end of the opposing linkage frame 71 is fixed with multiple sets of distributed lifting rollers 78 according to the gap area between the guide roller frames 62, and the opposing linkage rods 76 installed at both ends of the linkage fixed shaft 75 are suspended by the traction link 77 installed at the protruding end of the opposing linkage frame 71. The traction link 77 itself is installed on the opposing linkage frame 71, while the other end is slidably embedded in the slide groove structure of the opposing linkage rod 76 and embedded with a reset-driven retaining spring structure. At the same time, a balancing limit strip is installed according to the rotation trajectory of the opposing linkage rod 76 to limit the excessive rotation of the opposing linkage rod 76.The opposed linkage rods 76 distributed at both ends of the linkage fixed shaft 75 can be rotated and leveled by the traction link 77, and the jacking rollers 78 fixed on the linkage fixed shaft 75 can also rise or fall in a horizontal state when following the displacement of the drive chain condition 4. When a set of reciprocating jacking mechanism 7 arrives below the receiving guide roller mechanism 6 along the drive chain condition 4, the jacking rollers 78 contained therein will simultaneously be embedded in the adjacent gaps between the guide roller frames 62 and lift the goods gathered in rows on the jacking guide roller frames 62. Similarly, multiple sets of reciprocating jacking mechanisms 7 installed on the drive chain condition 4 can reciprocate to lift the goods gathered on the guide roller frames 62 until the reciprocating jacking mechanism 7 rises to a specific height of the jacking and stacking mechanism 8. When the jacking and stacking mechanism 8 is adjusted to the required transfer height, the reciprocating jacking mechanism 7 that has lifted the goods will follow the drive chain condition 4 to approach the height of the central inclined platform 84 and the conical resistance block 83. When the lifting device 77 moves away from the conical stop 83, the retaining spring structure installed between the chute of the pulling link 77 and the opposing linkage rod 76 drives the pulling link 77 to return to its original position and re-balance.

[0047] Please see the attached Figure 1 -Attached Figure 13The jacking and stacking mechanism 8 is located on the elliptical storage rack 3, and cooperates with the screw output structure of the top rack 2, the side frame 61, the traction link 77 and the jacking roller 78 to receive and stack the goods to be transferred. The jacking and stacking mechanism 8 includes a jacking frame 81, a parcel linkage frame 82, an output guide roller group 86 and a step-by-step descending component. The jacking frame 81 is fixedly connected to the side of the parcel linkage frame 82 close to the receiving guide roller mechanism 6, and the parcel linkage frame 82 is sleeved and slid on the outer surface of the top rack 2. The top of the jacking frame 81 close to the parcel linkage frame 82 is fixedly connected to the top of the central inclined platform 84. The inclined plate structure of the central inclined platform 84 is provided with through grooves corresponding to the distribution of the jacking rollers 78. The side of the jacking frame 81 away from the parcel linkage frame 82 is fixedly connected to the positioning slide 85, and the output guide roller group The cam 86 slides inside the lifting frame 81 through the positioning slide 85 and is located in the output direction of the central inclined platform 84. The step-by-step descending components are distributed on the side wall of the lifting frame 81 away from the wrapping linkage frame 82. An internal threaded sleeve structure is provided on one side of the wrapping linkage frame 82, and is threadedly sleeved on the screw output structure of the overhead frame 2. The inner side wall of the wrapping linkage frame 82 is also located on the displacement trajectory line of the traction link 77 and is fixedly connected with conical resistance blocks 83 on both sides opposite to each other. The step-by-step descending components include multiple groups of mutually hinged scissor-type brackets 87. The top end of the top scissor-type bracket 87 is relatively slidably embedded in the top wall of the lifting frame 81, and the bottom end of the bottom scissor-type bracket 87 is relatively slidably embedded in the side wall of the output guide roller group 86. The cross-end points of the scissor-type brackets 87 are rotatably connected with the extension platform 88. A retaining spring structure is connected between adjacent extension platforms 88, and the lifting and stacking mechanism 8 includes a lifting frame 81 installed on the transfer structure and a parcel linkage frame 82 for the lifting and stacking mechanism 8 to lift and move itself. The lifting frame 81 is fixed on the parcel linkage frame 82 and embedded in the angle area reserved at the top of the bottom frame 1, and the parcel linkage frame 82 itself is sleeved on the outer surface of the top frame 2. At the same time, the internal threaded sleeve structure installed on the parcel linkage frame 82 is docked with the screw output structure installed on the top frame 2. When the screw output structure is in operation, the parcel linkage frame 82 and the lifting frame 81 itself can be controlled to rise or fall along the top frame 2 to change different transfer heights, and the side wall of the lifting frame 81 facing the top frame 2 is equipped with a central inclined platform 8 that can guide the transportation of goods. 4. Its own guiding inclined plate structure is equipped with multiple sets of through slots for the lifting rollers 78 to pass through according to the distribution displacement of the lifting rollers 78, and the inner side of the lifting frame 81 is equipped with tapered abutment blocks 83 on both sides according to the installation height of the central inclined platform 84 and the displacement trajectory of the traction link 77. When the lifting and stacking mechanism 8 is adjusted to the required transfer height, the reciprocating lifting mechanism 7 holding the goods will follow the driving chain condition 4 to move closer to the height of the central inclined platform 84 and the tapered abutment blocks 83. When the traction link 77 rises and touches the tapered abutment blocks 83, the stationary tapered abutment blocks 83 will drive the traction link 77 to rotate and press down along the opposite linkage frame 71, and push the opposite linkage rod 76 and the linkage fixed shaft 75 to rotate and press down along the slide groove of the opposite linkage rod 76.When the lifting roller 78 that has lifted the goods and is fixed on the linkage fixed shaft 75 reaches the central inclined platform 84, it will rotate with the linkage fixed shaft 75 and form a certain slope, driving the goods lifted in a row to enter the central inclined platform 84 synchronously along the lifting roller 78, and the tapered interference block 83 can adjust different interference heights according to the lifting frame 81, so that the triggering of the tilt state of the reciprocating lifting mechanism 7 itself can follow the height change of the lifting and stacking mechanism 8. When the traction link 77 is away from the tapered interference block 83, the traction link 77 and the opposite linkage rod 76 slide The spring structure installed between the slots will drive the traction link 77 to reset and rebalance, and the goods transferred in rows to the central inclined platform 84 will continue to enter the lifting frame 81 along the central inclined platform 84, and finally fall on the guide roller area of ​​the output guide roller group 86 that moves up and down along the positioning slide 85 in the lifting frame 81. The output guide roller group 86 is also responsible for stacking the fallen goods for transfer and transportation. With the cyclic lifting of multiple groups of reciprocating lifting mechanisms 7, goods in different rows begin to be stacked on the output guide roller group 86, and the output guide roller group 86 is stacked as the received goods move up and down. As the weight increases, the stacking mechanism 8 begins to gradually descend under the restriction of the step-by-step descending assembly included in the stacking mechanism 8 to match the stacked goods. The step-by-step descending assembly includes multiple sets of mutually hinged scissor brackets 87, and the extension platform 88 installed at the hinge point of the scissor bracket 87 fixes a set of retaining spring structures between two adjacent sets of scissor brackets 87. The top scissor bracket 87 is installed on the top wall of the lifting frame 81, and the bottom scissor bracket 87 is suspended on the output guide roller group 86. When the output guide roller group 86 is continuously moved along the stacking height due to the increase in the stacking height, the stacking mechanism 81 is gradually lowered. As the positioning slide 85 descends, the mutually hinged scissor-type brackets 87 begin to expand simultaneously along the jacking frame 81 and the output guide roller set 86. The spring structure between the extension platform 88 is also pulled, allowing the output guide roller set 86 to slowly descend, and at the same time increasing the buffering force for falling goods. After the stacked goods are transferred and transported, the multiple sets of spring structures, which have lost their pulling force, will begin to pull the extension platform 88 and the configured scissor-type brackets 87 to retract, and pull the output guide roller set 86 back to the output position of the central inclined platform 84.

[0048] Working principle: First of all, this equipment is mainly used for the lifting and transshipment operations in cargo transportation. At the same time, during the lifting and transshipment process, stacking operations can be carried out synchronously. The overall structure is installed according to the bottom rack 1 and the top rack 2, and the top rack 2 is installed on one side of the bottom rack 1, so that the top of the bottom rack 1 can retain an angle area, and the elliptical rack 3 that limits the operation of the drive chain condition 4 is installed in line on the outside of the top rack 2, so that the drive chain condition 4 can operate inside the top rack 2 through the elliptical rack 3. The input guide roller group 5 for cargo input is installed on the side wall of the bottom rack 1, which can guide the cargo to be transferred to the receiving guide roller mechanism 6 inside the bottom rack 1, and the multiple sets of reciprocating jacking mechanisms 7 installed at the chain end of the drive chain condition 4 can synchronously Following the operation of the drive chain condition 4, the jacking and stacking mechanism 8 that rises and falls along the outer surface of the top rack 2 can drive the reciprocating jacking mechanism 7 to change its shape, so as to guide the goods into the jacking and stacking mechanism 8, and then the goods are lifted and stacked and transported by the jacking and stacking mechanism 8. First, the side frame 61 included in the receiving guide roller mechanism 6 is installed on the side of the bottom rack 1 away from the elliptical rack 3, so that the elliptical rack 3 fixed on the top rack 2 and the drive chain condition 4 can operate in independent areas, and the other end of the multiple sets of guide roller frames 62 installed on the side frame 61 is installed on the bottom rack 1 through an independent bracket structure, so that the gap area between adjacent guide roller frames 62 is open, and the trapezoidal guide frame 63 installed on the side frame 61 is fitted on the guide roller frames 62. The inclined surface can guide the goods fed by the input guide roller group 5 to align and approach the side of the guide roller frame 62, and gradually gather into a row on the side of the guide roller frame 62 close to the elliptical storage rack 3, and the reciprocating jacking mechanism 7 includes adjacently arranged opposing linkage frames 71 and linkage shafts 72, and the clamping shaft structure of the opposing linkage frame 71 and the clamping angle pieces 73 installed at both ends of the linkage shaft 72 are connected to each other through a chain link structure, so that when the clamping angle piece 73 is installed on the chain of the drive chain condition 4, it can bend according to the turning part of the chain, so that the clamping angle piece 73 can pull the opposing linkage frame 71 and the linkage shaft 72 to follow the chain end displacement of the drive chain condition 4, and the horizontal connecting rod 74 sleeved between the linkage shaft 72 and the clamping shaft structure of the opposing linkage frame 71 makes When the opposed linkage frame 71 and the linkage shaft 72 follow the displacement of the engaging angle piece 73 to the vertical end of the chain structure of the drive chain condition 4, the opposed linkage frame 71 can be supported to a horizontal state along the linkage shaft 72, so that the opposed linkage frame 71 can always maintain a horizontal rise when it is vertically displaced, and the linkage fixed shaft 75 installed at the outer end of the opposed linkage frame 71 is fixed with multiple sets of distributed lifting rollers 78 according to the gap area between the guide roller frames 62, and the opposed linkage rods 76 installed at both ends of the linkage fixed shaft 75 are suspended by the traction link 77 installed at the protruding end of the opposed linkage frame 71. The traction link 77 itself is installed on the opposed linkage frame 71, while the other end is slidably embedded in the slide groove structure of the opposed linkage rod 76, and is embedded with a resetting drive spring structure.At the same time, a balancing limit bar is installed according to the rotation trajectory of the opposing linkage rod 76 to limit the excessive rotation of the opposing linkage rod 76, so that the opposing linkage rods 76 distributed at both ends of the linkage fixed shaft 75 can be rotated and leveled by the traction link 77, and the jacking roller 78 fixed on the linkage fixed shaft 75 can also rise or fall in a horizontal state when following the displacement of the drive chain condition 4. When a set of reciprocating jacking mechanisms 7 arrives below the receiving guide roller mechanism 6 along the drive chain condition 4, the jacking rollers 78 it contains will simultaneously embed into the adjacent gaps between the guide roller frames 62 and lift the goods gathered in rows on the jacking guide roller frames 62. By analogy, multiple sets of reciprocating jacking mechanisms 7 installed on the drive chain condition 4 can reciprocate and lift the goods gathered on the guide roller frames 62 until the reciprocating jacking The mechanism 7 rises to a specific height of the jacking and stacking mechanism 8, and the jacking and stacking mechanism 8 includes a jacking frame 81 installed on the transfer structure and a parcel linkage frame 82 for the lifting and stacking mechanism 8 to move up and down. The jacking frame 81 is fixed on the parcel linkage frame 82 and embedded in the angle area reserved at the top of the bottom frame 1, and the parcel linkage frame 82 itself is sleeved on the outer surface of the top frame 2. At the same time, the internal threaded sleeve structure installed on the parcel linkage frame 82 is docked with the screw output structure installed on the top frame 2. When the screw output structure is in operation, the parcel linkage frame 82 and the jacking frame 81 itself can be controlled to rise or fall along the top frame 2 to change different transfer heights, and the side wall of the jacking frame 81 facing the top frame 2 is equipped with a central inclined platform that can guide the transportation of goods. The guide inclined plate structure 84 is provided with a plurality of through slots for the lifting rollers 78 to pass through according to the distribution displacement of the lifting rollers 78, and the inner side of the lifting frame 81 is provided with tapered abutment blocks 83 on both sides opposite to each other according to the installation height of the central inclined platform 84 and the displacement trajectory of the traction link 77. When the lifting and stacking mechanism 8 is adjusted to the required transfer height, the reciprocating lifting mechanism 7 carrying the goods will follow the drive chain condition 4 to approach the height of the central inclined platform 84 and the tapered abutment blocks 83. When the traction link 77 rises and contacts the tapered abutment blocks 83, the stationary tapered abutment blocks 83 will drive the traction link 77 to rotate and press down along the opposing linkage frame 71, and push the opposing linkage rod 76 and the linkage fixed shaft 75 to rotate and press down along the slide groove of the opposing linkage rod 76. When the lifting roller 78 that has lifted the goods and is fixed on the linkage fixed shaft 75 reaches the center inclined platform 84, it will rotate with the linkage fixed shaft 75 and form a certain inclination, driving the goods lifted in rows to enter the center inclined platform 84 synchronously along the lifting roller 78, and the tapered interference block 83 can adjust different interference heights according to the lifting frame 81, so that the triggering of the tilt state of the reciprocating lifting mechanism 7 itself can follow the height change of the lifting and stacking mechanism 8. When the traction link 77 is away from the tapered interference block 83, the retaining spring structure installed between the traction link 77 and the slide groove of the opposite linkage rod 76 will drive the traction link 77 to reset and re-balance, and the goods transferred in rows to the center inclined platform 84 will continue to enter the lifting frame 81 along the center inclined platform 84.And finally falls on the guide roller area of ​​the output guide roller group 86 that moves up and down along the positioning slide 85 in the jacking frame 81, and the output guide roller group 86 is also responsible for stacking the fallen goods for transfer and transportation. With the cyclic lifting of multiple sets of reciprocating jacking mechanisms 7, goods in different rows begin to be stacked and stacked on the output guide roller group 86, and as the weight of the received goods increases, the output guide roller group 86 also begins to gradually descend under the restriction of the step-by-step descending component included in the jacking and stacking mechanism 8 to match the continuously stacked and stacked goods. The step-by-step descending component includes multiple sets of mutually hinged scissor brackets 87, and the extension platform 88 installed at the hinge point of the scissor bracket 87 fixes a set of spring structures between two adjacent sets of scissor brackets 87. The top scissor bracket The bracket 87 is mounted on the top wall of the lifting frame 81, and the scissor bracket 87 at the bottom is suspended on the output guide roller group 86. When the output guide roller group 86 continues to descend along the positioning slide 85 due to the increase in stacking height, the mutually hinged scissor brackets 87 begin to expand simultaneously along the lifting frame 81 and the output guide roller group 86, and the retaining spring structure between the extension platform 88 is also pulled, allowing the output guide roller group 86 to slowly descend, and at the same time increasing the buffering force for falling goods. After the stacked goods are transferred and transported, the multiple sets of retaining spring structures that have lost their pulling force will begin to pull the extension platform 88 and the configured scissor bracket 87 to retract, and pull the output guide roller group 86 back to the output position of the central inclined platform 84.
